To all wtomz'tf/nag/ concern. i Y

Be it known that l, ARMAND H. lnroun,l a citizen of the'r United States, residingat Chicago, in the county of C'ook and State of Illinois, have invented certain-new' and useful Improvements in Brake Mechanism, of which the following is a specification.

This invention relates to brake mechanism, and more particularly to means for supporting and leveling brake beams.

The object of this invention is to simplify and improve means for supporting and leveling brake beams in a manner to meet the various requirements for successful commercialoperation.A Y i This and other objects are accomplished by Vmeans of the arrangement'disclosed on the accompanying' sheet of drawings, in which- Y Figure 1 is a fragmentary side elevation f a railway car truck embodying my in! vention; l

Figure 2 is a fragmentary front elevation of the same arrangement;

Figure 3 is a detail perspective view of a bracket for supporting one of the rigid safety bars; and

Figure 4 is a side elevation of the combi- .nation bracket and leveling spring.

Referring to the figures of the drawings, it will be noted that I have disclosedr my invention'in connection with arailway car truck including a spring plank which,

Vas is well known in the art, extends trainsversely of the truck. Brakebeanis 11 are provided, the brake beams in this easebe-l and is supported beneath the spring plank.

10. Means for supporting these rigid safety bars' in their opera-tive positions takes the form of two different types of bracket members. The left hand bracket member 18,

as shown in Figure 2 and shown in perspective in Figure 8 is orovided with an uwer i: a l ll hook pprtion 19, which hooks over the as-Y sociated vertical flange of the spring-piank,

theV lower portion of the bracket having anvv opening for the reception of the safety bar, the extreme lower portion of the bracket 18 having an offset portion 21 to provide a relatively large seat ror the safety bar. The bracket 18 is secured to the spring` plank by a rivet or bolt 22which passes through an opening 23V 1n the bracket.

The right hand safety guard, asviewed in 1F igure 2, is supported by a combination v Y bracket and leveling spring, the bracket portion being 1n the form of a spring doubled v back cn itself, as shown in Figure 4, the

.upper end of the bracket being provided with ahook 24 for hooking over the associated vertical flange ofthe spring plank, said bracket member having an opening 25 for the reception of the rigid safety bar and having at its'lower end a head 26 providing a large bearing surface for the Vvsafety bar. This bracket member ,is secured to the spring plankA 'by a suitable rivet or bolt which extends through 'the opening 27. This supporting bracket terminates in along spring 28 which extendsV from a position over `a safety bar at one side of-thetransverse center of the brake beam, said spring extending angularly to the transverse center of the brake'beam, where it is connected at 30 by a link 29 to the fulcrum member 14 over the Ytransverse center of the tension member 13.

The lower eye l31 of the link 29 extends in a central longitudinal ,plane with respect to` the truck, and the uppereye32 0f the link extends at an angle to accommodate the eye 33'at the upper and outerfend of the spring 28. This spring 28 yieldably'supports the outer endv or tension rod side of the brake tion, whereby the4 brake shoes and braking surfaces of the associated wheel may come into proper operative association when the brakes are set.

By providing the composite bracket and leveling spring having relatively offset portions, tlie numberof single brackets is reduced and thegstructure simplified. For

each truck, two braekets18, such as shown inV Figure 3, are used,`and two brackets, such as shown in Figure 4, areused.' Lock springs l84 which arel secured tothe safety barsflT engage portions vof the .brackets `to preventv accidental displacement of said safety bars.

U5 beam to maintain the latter in a. level posif It is my intention to cover all modificatiens of the invention 'falling Within the spirit and scope 'oi'f the following` claims.

I claim:

l. ln brake mechanism, a` spring plank,

L combination bracket and leveling' spring secured thereto, :i safetyY bar supported by seid bracket, and a brake beam, the trnsverse middle portion of which is supported by the leveling sprino' which extends tramsH versely or the om' irom the bracket por-V tion.- f o v Y,

2. in brake mechanism, the combination ol the tension member, and a connection be-V tween said leveling spring Iand tension meniber. i
